Christine,
the nosy reporter who is having an affair with Quinn, turns out to
be the daughter of
Arthur Mitchell, the Trinity Killer.

In
an attempt to protect her serial killer father, she has shot
and killed Agent Lundy (who was investigating the Trinity case),
and she now fears that the police may be closing in on her.

So,
in this scene, we see her cell phoning her distant father while she's driving.

He
receives the call while he is busy loading cement into the back of his
car, at a "Hardware Contracting Supply" company. (That cement
will play a role later in the same episode.)

Obviously
frightened, she tells him she really needs to see him (apparently he only
sees her
about twice a year), but he coldly dismisses her pleas and hangs up on
her.

She
begins to break down and cry, pitifully sobbing (to herself): "I think
I'm in trouble..."

Q.
What is it actually in real life?

A. At least
two different streets, plus a studio lot.

Q.
Where can I find it in real life?

A. This phone
scene was shot in a number of different locations, then patched together:

One of the
clips of Christine talking (while driving) was shot with her car heading
west on Willow Street, in Signal Hill,
CA (near Long Beach).Look carefully at the second photo from the top, and you'll
see her pass a large "Howard's"
TV store. That store is at 3300 E. Willow.(An aerial
photo.)

(Not coincidentally, that's
very close to the city tow yard, where they
took Dexter's car after his accident.)

But the next clip of her
talking while driving is several miles away (see the fourth photo from
the top). This time, she's heading north on Atlantic
Avenue (in Long Beach). She comes to a stop (while crying)
next to a medical/dental office building at 3759 Atlantic Ave,
just south of Bixby Road. (An
aerial
photo.)

Meanwhile,
Trinity's "hardware store" is actually just a quickly-constructed
outdoor set in the south portion of the Sunset-Gower
studio lot, where they film "Dexter".
In fact, it's the same corner where they often create the outdoor catering
truck scenes for the Miami police
station.(An
aerial
photo.)

If you look closely,
as Trinity's loading his car (see the top photo), you'll glimpse a sign,
on a white building in the background, reading "Fountain Avenue
Market". That market is at
6010 Fountain Avenue, in Hollywood,
literally right across the street (south of) the studio's low south
wall. (An aerial
photo.)

The
market is located in a strip mall that "Dexter" producers have
used several times before. In the second season, they used the east end
of that strip mall as the Swamp Bar.
In the third season, they used the other (west) end of the strip mall as
the tailor shop where Dexter picked
up his wedding tux - and was abducted by The Skinner (see the upholstery
shop in the photo below). It was also used in the second season as the
interior of the voodoo shop in the second season, where Dexter fails to
kill a voodoo priest.

The
Fountain Ave Market is located just to the left of the tailor shop/upholstery
store, as you can see below.

A. It
was easy to spot the large Howard's store in the first Christine shot.
And Google
StreetView confirmed that the Signal Hill/Long Beach store
on Willow (near the tow yard) was the right Howard's.

The
second Christine location took a little more effort. But fortunately, the
street number (3759) was visible on a building behind her, so it was just
a matter of tracking down the right street. After checking Long Beach street
numbers, I found the 3700 blocks in the Bixby area. I knew that they had
filmed in that area this season, so it was an obvious possibility. Google StreetView
let me find the matching street there.

As
for Trinity's location, I almost certainly would have spotted the Fountain
Avenue Market on my own, but a fan, Jeff,
beat me to it, emailing me about it before I even had a chance to watch
the episode. (Thanks, Jeff!)
